This PCI solution delivers you the lowest cost Flash SSD capacity, with drop in comvenience.

We have tested this in our own data center using an IMAP/SMTP mail server with about 11gb a day of incoming mail, and a total mail database of approximately 52gb in a 64gb flash space. At a free space level of approximately 22% free space, we are getting average wear efficiency on the mail server of about 35 percent, and the application has a projected wear life of 22 years.

The installation in this case consists of 2 cards each with a pair of 32gb flash cards on them, mirrored. Performance has been superb. The device, which replaced mirrored 7200 rpm drives, delivers about 2200 8kb reads per card node, or about 8,800 random reads all together. The write rate is spread over 2 cards, and amounts to about 5,000 8kb random writes a second. More detailed performance results, per chip, are shown at the bottom of this page.

You can buy this card pre-assembled with appropriate card counts and MFT bundled in from the distributors listed below. Or if you want, you can shop the components yourself on the internet. The core of this unit is the Addonics AD4CFPRJ 4 CF card holder, shown above, which you can buy from Addonics, or elsewhere. We add to that 2 to 4 Pieces of Ridata 233x 16gb or 32gb CF Cards. The 16gb part number is CFR16G-233X-LIG2. The 32gb part number is CFR32G-233X-LIG2. Click either link to Google-search the best price. Both components are made with 10,000 erase cycle MLC Flash Memory.

Important Note: this controller holds 4 CF cards but operates master/slave. Thus, performance is halved if more than two drives are used, or if the two CF Card "drives" installed are in the same master/slave circuit. This solution is fine in a Linux environment. Because the PCI card is very "dumb" many Windows systems may be unable to use it except in a mirrored or RAID-10 environment.
